The Black Opal from Sealy offers a very medium-firm sort of feel.  It uses a pocketed, or "wrapped," style innerspring that allows for good conformity and motion deadening characteristics, but the upholstery layers are a tad on the firmer side.  The Black Opal is an excellent option if you're looking for a medium-range bed that offers a bit of comfort for everyone.  Also, if you're at slightly different ends of the comfort spectrum from your sleeping partner, this might be a good option for you.


Designed as an entry-level, adult-support mattress, the Black Opal has support enough for adults, but it isn't really intended to be a long term-type mattress.  So why do we classify it adult-support but not "long term" at the same time?  This is primarily due to the grade of the materials used in the bed. Reasonable life expectancy out of this mattress should be in the range of around 7-9 years, depending on the frequency of use, care it receives, and ultimately the size of the people on the bed.  

These features make the Black Opal very popular for guest rooms, older children, college students, and adults alike.
